f f The driving 'means' fand all "otherfdetails ofthe helicoidal members 'are fullyxshown'anddescribed Due to the positioning of the helicoidal members, in pairs, at opposite sides of, and above the stack of web plies, it will be apparent that a fold of the web in falling toward the stack alights first on an upper coil of its adjacent helicoidal member, and said member, in rotating, worms the fold downwardly until said fold is brought under the lowermost convolution, which presses or compacts it on the top of the stack to which it is added.

In theview of a stack of folded web shown in Fig. 3 the lines Y indicate the slits produced therein by the circular knives 53, and at 54 there appear the slight connections left in the web by the nick with which each knife is provided.

The art as previously knownincluded no means for severing tape widths from Wider widths of web, and, as a matter of fact it has not been found practicable to cut through a stack of folded plies of paper web of more than three inches in height in attempting to produce stacks of folded tape.

Nor was it heretofore possible to create stacks, of continuous tape, because a web of tape width if allowed to fall in folds in an attempt to build a stack thereof, would be uncontrollable so far as previously existing mechanisms are concerned.

` Therefore it has remained for me to slit the paper web into tape widths, without separation, whilst the web is passing through the folding and stacking machine, leaving the tape connections of so slight a character that stacks of tape can readily be broken apart'from a web stack of relatively great height.

The slight and insignificant edge projections left upon a compacted stack of paper tape that has been broken away from a main stack of paper web are easily removable by brushing.

Variations within the spirit and scope of my invention are equally comprehended by the foregoing disclosure.

I claim:-

1. The method of producing stacks of folded paper tape from a web of paper which consists in partially slitting the web into tape widths during passage from a web source to a receiving support, guiding the web in its passage, indenting said web to create folds therein, causing the folded plies to fall successively upon the support to form a stack of partially slit continuous web, and compacting the folds to provide a hard, edgewise surface on all four sides of the stack.

2. The new product which consists of a stack of continuous, uninterrupted, partially slit paper web, for separation into tape widths, said web having zigzag foldsof equal length and being approximately in the form of a rectangular block, the edges of all the folds being in perfect alignment, and said folds being compacted together to provide a hard, edgewise surface, on all sides of the block.
